Arsenal have agreed a fee with Celtic over the transfer of defender Kieran Tierney.
The left-back is on his way to London and looks set to sign ahead of Thursday's Premier League deadline, according to Sky Sports.
Arsenal's initial £15m bid for Tierney was rejected in June, as was a second £25m offer, as it contained too many add-ons and was dependant on the Gunners qualifying for the Champions League.
The 22-year-old, who has won five Scottish Premiership titles, made 40 appearances in all competitions for the Hoops during the 2018/19 campaign.
If Arsenal are able to complete the deal for Tierney he would be Unai Emery's fifth signing of the summer window.
Celtic boss Neil Lennon hopes he will be allowed to reinvest Kieran Tierney's record £25million transfer fee.
The Hoops boss was busy overseeing his team's 1-1 Champions League draw with Cluj as reports broke that a deal had been struck with Arsenal to make Tierney Scotland's most expensive ever footballer.
Asked if he was expecting to see the profits to spend on his team, Lennon told BBC Radio Scotland: "I hope so. There are a few areas that I'd like to improve in.
"If that is the case then he goes with everybody's best wishes. He's a superb player and will be a big loss to us.
"It shows the work that people have done at the club, whether it be Brendan Rodgers, Ronnie Deila or the people at the academy to produce such a fine player. He's an outstanding young talent and a great kid.
"I don't know (if a deal has been agreed) but like I've said the last few days it wouldn't surprise me. These things tend to naturally take their course, so we'll have to wait and see. I've not had any confirmation at all."
